Excellent for framing
Used these for a workbench build using 3030 profiles. They slid in smoothly and held the bolts securely without stripping.

Smooth sliding action
They fit the T-slot perfectly. I was worried they might be too loose, but the grip is just right for adjustable positioning.

Good but tight fit
Quality seems solid. Required a little force to slide them into the channel initially, but once in place, they are very stable.

Strong hold
No slipping under load. I used these for a machine guard frame and everything stays tight even with vibration.

Great value
Better than what I found at the local hardware store. The zinc coating looks uniform and the threads are clean.
Q: Can I reuse them?
A: Yes, they can be slid out and repositioned along the profile channel easily.
Q: Is the thread internal or external?
A: These have internal threads designed to accept standard M6 bolts.
Q: Will these work with 4040 profiles?
A: These are best suited for 2020 and 3030 series profiles. For 4040, please check our larger block nut listing.
Q: Are they rust resistant?
A: The zinc plating offers basic corrosion resistance suitable for indoor use.
Q: What bolt size fits these?
A: M6 bolts are compatible with this set. Ensure the bolt length is appropriate for your profile thickness.
